How fun is DFO?

The PvP system in DFO is amazing. I haven't played WoW, but I can say that DFO is all about real-time strategy and having direct control of your character. You need to know your opponent, utilize the cooldown times of your skills, execute combos to prevent your opponent from countering, etc. And remember, both you and your opponent are simultaneously trying to accomplish these tasks, so it gets intense.

The variety of the classes is also amazing. Every class is unique, with different play styles and different tactics in battle.
